imma have to also say like some other did, you need a higher launch...so if its burnin rubber with a higher, id say upgrade the suspension, or play with the trac. bars. maybe a diff set of rubber.

if it's better in the long run to get a 282 instead of buying the 1.7 roller rockers for this thing then let me know, the car gets driven almost every day and has great street manners.
i also forgot to mention... plz don't laugh..
i run a 2 1/4" exhaust.. haha - i was thinking of going to 3 but i don't know

try some better traction bars like slid a link,or cal tracs or no affense do you have the money,cuz the slid-a-links are like $300-$350.i have no idea how much the cal tracs are but id imagine they are $400-$500 or more.also if you do have the money id go with heavier duty leaf springs and the cal tracs.just my .02

already got the heavy duty leaf springs, and the cal tracs are alright but not for me, the original style traction masters are a solid bar which work unbelieveably well. i think i might go with some competition engineering drag struts/shocks though

well, i'm posting in here again since most of you guys are more engine orientated than most in the classic section.
heres what i'm running
331 stroker 9.5-6:1 compression
edelbrock performer rpm heads
edelbrock performer rpm intake
1" 4 hole spacer
Holley 670 street avenger (70/73s, lightest spring blue pump cam #2)
headman longtube headers
comp cams xe276hr w/ 1.6 rockers
running in a 67 mustang w/ C4 - 3.73 rear / 2800-3000 stall with traction bars etc. blah blah
i cut a 1.8 60' time with the bars after a good heat up of the tires, launched at around 1000-1200 rpm and shifted @ 6000.
track died later on so i was hitting 1.9's and 1 2.0 but still ran a 12.65 @ 108, 12.7 and another 12.6 all at the same speed.
i cannot get off the line with any more rpm's it will just light the tires up, i run 275/50/15 bfg drag radials with about 20 passes on them and i do a healthy burnout. tires are at 10-12 psi.
now my main thing is, i have a cam that was designed for 1.7 rockers. if i moved to the 1.7's am i going to gain anything that i have lost, and also if i moved to a open hole spacer instead of a 4 hole?
i'd think my car would be making more power than what the times tell me, my car is 2982 lbs with me in it. - so any help would be appreciated before i dump some money into rockers or anything if it's not gonna make a diff.

You also have high 60' numbers, yet that 108 MPH trap speed would be able to optimally give you an ET of 12.6s...... what does that tell you regarding what's happening to the engine through the 1320'?

^^^maybe for a 302 set up but not the most optimal for a stroker and as for the intake an Rpm is fine I have an rpm air gap on my 85 with 185 heads and 347 bottom end and it pulls hard...11.50's @118+ full weight car

yeah, the heads should be fine, i got em in a deal and had em ported so i doubt they are flowing anything low. i had a card with the #'s but iirc they flowed just over the 185's which is fine. i've thought of the intake but i was told not to, either was going with the xcelerator or a victor jr. but everyone said "no"
not much i can do about the carb unless someones got a 750 or something and wants to trade (also got a 600 to toss in too)
